About
01 / SUBJECTI'm a Software Engineer based in Sheffield, with commercial experience building production systems at DMS Navigator. My work spans C#, .NET, client-facing applications, data-backed workflows and the practical decisions that make software hold up after launch.
Alongside my day job, I build DugsiCore for school administration in Somaliland, Vormation for private squad analytics, and Xisaab for small-business invoicing. My current focus is software architecture, application design and developing these products further.
Outside of engineering, I've modelled since 2022, walking London Fashion Week, shooting with Kurt Geiger, and appearing on the Vogue runway. Before tech, I spent eighteen months on a sponsored outdoor leadership programme across the Lake District, Peak District, and Wales, coming away with a Climbing Wall Instructor qualification, Outdoor First Aid, Mountain Bike Instructor training, and a Duke of Edinburgh Gold Award. Back in Sheffield, I volunteer at Unity Gym and run weekend football sessions with kids in the community.

Work Case Study
03 / COMMERCIAL WORK
DMS NAVIGATOR · FEATURED CASE STUDY
Vehicle Health-Check System
A vehicle health-check system I built end-to-end: a desktop application captures the data, a mobile application supports technicians on site, and a customer-facing web application makes the results visible to clients.
The workflow connects those surfaces back to the desktop application's billing and ledger accounts, turning a field process into a joined operational and financial record.

Billing & ledger integration
Loan Car · Courtesy Car System
A dedicated system for managing loan cars and courtesy cars, built as part of my work at DMS Navigator.

DugsiCore · School Administration
A live school management platform for small schools in Somaliland, replacing paper registers and fee ledgers with one place to manage students, classes, attendance and payments.
Teachers take attendance on their phones, while school admins manage enrolment, staff accounts and fees paid in cash or mobile money. Each school has its own separate workspace, with an operator console for school onboarding and account support.
